The penalty for losing a game of 8-ball (standard pool) without potting a single ball is to walk around the table with one's pants down (or skirt up), according to official pub rules. This counts for any loss, including accidental sinking of the eight ball.

Alternative to the outdated term "Hands down" to convey a statement with absolute conviciton and certainty. "Pantsdown" was originally coined by centaurs in Middle Earth due to their physical inability to wear pants despite the group's strong desires to do so.
